  • the application of such tread layers mostly takes place by means of thermal spraying, for example electric arc wire spraying.
  • Arc wire spraying is an arc generated by applying a voltage between two wire-shaped spray materials.

  • Microalloys are those alloys which are predominantly made up of one constituent, which in relation to a total mass only small amounts of other constituents
  • Fine-grained pearlite consisting of hard Fe3C and ferrite, is a tribologically positive effective phase.
  • Bainite is a conversion phase of medium hardness and wear resistance.
  • Martensite is a hard, wear-resistant ⁇ structure. The formation of martensite may be due to the nature of the cooling of the spray material and by the choice of the alloy components of the microalloying be specifically influenced.
